Screen flow-control interferes with the {{Keypress|Ctrl-q}} mapping (see: [[#Redundant mapping|Redundant mapping]]). To disable it add the following to {{ic|~/.screenrc}}:

−

defflow off

−

−

An alternative is to escape the command and send it directly to rTorrent. In other words, use {{Keypress|Ctrl-a}} {{Keypress|q}} to quit rTorrent within GNU Screen.

To automatically start rTorrent within Screen, add the following to the {{ic|~/.screenrc}} configuration file:

−

screen -t rtorrent rtorrent

{{note|See the rTorrent wiki article on this subject for more information: [http://libtorrent.rakshasa.no/wiki/RTorrentCommonTasks#StartingrTorrentonSystemStartup Starting rTorrent on System Startup]}}

Make sure to change USER to the username that will be running rtorrent.

−

Make the file executable:

−

# chmod +x /etc/rc.d/rtorrent

−

−

Creating a {{ic|.rtorrent.rc}} file with relative paths in a user's home directory will break the rc.d script. To run multiple instances of rTorrent with relative paths under different users, replace line 9 in {{ic|/etc/rc.d/rtorrent}} with the following:

To run the daemon user multiple users create one rc.d script for each user. Then replace line 9 in {{ic|/etc/rc.d/rtorrent}} with the following:

−

su - username -c 'killall -w -s 2 /usr/bin/rtorrent' &> /dev/null

−

−

To connect to the daemon process on a remote machine use [[Secure Shell|SSH]]:

−

$ ssh -t rtorrent@192.168.1.10 'screen -r'

−

−

Or if you used [[tmux]] instead of [[screen]]:

−

$ ssh -t rtorrent@192.168.1.10 'tmux attach -t rtorrent'

−

The check_hash option executes a hash check when a torrent download is complete or rTorrent is started. When starting, it checks for errors in your completed files.

check_hash = yes

Create and manage files

The directory option will determine where your torrent data will be saved. Be sure to enter the absolute path, as rTorrent may not follow relative paths:

directory = /home/[user]/torrents/

The session option allows rTorrent to save the progess of your torrents. It is recommended to create a directory called .session (e.g. $ mkdir ~/.session).

session = /home/[user]/.session/

The schedule option has rTorrent watch a particular directory for new torrent files. Saving a torrent file to this directory will automatically start the download. Remember to create the directory that will be watched (e.g. $ mkdir ~/watch). Also, be careful when using this option as rTorrent will move the torrent file to your session folder and rename it to its hash value.

The following schedule option is intended to stop rTorrent from downloading data when disk space is low.

schedule = low_diskspace,5,60,close_low_diskspace=100M

Port configuration

The port_range option sets which port(s) to use for listening. It is recommended to use a port that is higher than 49152 (see: List of port numbers). Although, rTorrent allows a range of ports, a single port is recommended.

Additional settings

The encryption option enables or disables encryption. It is very important to enable this option, not only for yourself, but also for your peers in the torrent swarm. Some users need to obscure their bandwidth usage from their ISP. And it does not hurt to enable it even if you do not need the added security.

This final dht option enables DHT support. DHT is common among public trackers and will allow the client to acquire more peers.

dht = auto
dht_port = 6881
peer_exchange = yes

Note: See the rTorrent wiki article on this subject for more information: Using DHT

Key bindings

rTorrent relies exclusively on keyboard shortcuts for user input. A quick reference is available in the table below. A complete guide is available on the rTorrent wiki (see: rTorrent User Guide).

Note: Striking Template:Keypress twice in quick succession will make rTorrent shutdown without waiting to send a stop announce to the connected trackers.

Cmd

Ctrl-q

Quit application

Ctrl-s

Start download. Runs hash first unless already done.

Ctrl-d

Stop an active download or remove a stopped download

Ctrl-k

Redundant mapping

Template:Keypress is often used for terminal control to stop screen output while Template:Keypress is used to start it. These mappings may interfere with rTorrent. Check to see if these terminal options are bound to a mapping:

Pre-allocation

The rTorrent package in the community repository lacks pre-allocation. Compiling rTorrent with pre-allocation allows files to be allocated before downloading the torrent. The major benefit is that it limits and avoids fragmentation of the filesystem. However, this introduces a delay during the pre-allocation if the filesystem does not support the fallocate syscall natively.

Therefore this switch is recommended for xfs, ext4 and btrfs filesystems, which have native fallocate syscall support. They will see no delay during preallocation and no fragmented filesystem. Pre-allocation on others filesystems will cause a delay but will not fragment the files.

To make pre-allocation available, recompile libtorrent from the ABS tree with the following new switch:

Manage completed files

Note: Currently, this part requires either the git version of rtorrent/libtorrent or having applied the patch to 0.8.6 that adds 'equal'.

Note: If you're having trouble with this tip, it's probably easier to follow this

It is possible to have rtorrent sort completed torrent data to specific folders based on which 'watch' folder you drop the *.torrent into while continuing to seed. Many examples show how to do this with torrents downloaded by rtorrent. The problem is when you try to drop in 100% done torrent data and then have rtorrent check the data and resume, it will not be sorted.

As a solution, use the following example in your ~/.rtorrent.rc.
Make sure to change the paths.

# location where new torrent data is placed, and where you should place your
# 'complete' data before you place your *.torrent file into the watch folder
directory = /home/user/torrents/incomplete
# schedule a timer event named 'watch_directory_1':
# 1) triggers 10 seconds after rtorrent starts
# 2) triggers at 10 second intervals thereafter
# 3) Upon trigger, attempt to load (and start) new *.torrent files found in /home/user/torrents/watch/
# 4) set a variable named 'custom1' with the value "/home/user/torrents/complete"
# NOTE: if you do not want it to automatically start the torrent, change 'load_start' to 'load'
schedule = watch_directory_1,10,10,"load_start=/home/user/torrents/watch/*.torrent,d.set_custom1=/home/user/torrents/complete"
# insert a method with the alias 'checkdirs1'
# 1) returns true if the current path of the torrent data is not equal to the value of custom1
# 2) otherwise, returns false
system.method.insert=checkdirs1,simple,"not=\"$equal={d.get_custom1=,d.get_base_path=}\""
# insert a method with the alias 'movecheck1'
# 1) returns true if all 3 commands return true ('result of checkdirs1' && 'torrent is 100% done', 'custom1 variable is set')
# 2) otherwise, returns false
system.method.insert=movecheck1,simple,"and={checkdirs1=,d.get_complete=,d.get_custom1=}"
# insert a method with the alias 'movedir1'
# (a series of commands, separated by ';')
# 1) "set path of torrent to equal the value of custom1";
# 2) "mv -u <current data path> <custom1 path>";
# 3) "clear custom1", "stop the torrent","resume the torrent"
# 4) stop the torrent
# 5) start the torrent (to get the torrent to update the 'base path')
system.method.insert=movedir1,simple,"d.set_directory=$d.get_custom1=;execute=mv,-u,$d.get_base_path=,$d.get_custom1=;d.set_custom1=;d.stop=;d.start="
# set a key with the name 'move_hashed1' that is triggered by the hash_done event.
# 1) When hashing of a torrent completes, this custom key will be triggered.
# 2) when triggered, execute the 'movecheck1' method and check the return value.
# 3) if the 'movecheck' method returns 'true', execute the 'movedir1' method we inserted above.
# NOTE-0: *Only* data that has had their hash checked manually with ^R [^R = Control r].
# Or on a rtorrent restart[which initiates a hash check]. Will the data move; ~/torrents/incomplete => ~/torrents/complete for example.
# NOTE-1: 'branch' is an 'if' conditional statement: if(movecheck1){movedir1}
system.method.set_key=event.download.hash_done,move_hashed1,"branch={$movecheck1=,movedir1=}"

You can add additional watch folders and rules should you like to sort your torrents into special folders.

For example, if you would like the torrents to download in:

/home/user/torrents/incomplete

and then sort the torrent data based on which folder you dropped the *.torrent into:

notify_me is the command id, which may be used by other commands, it can be just about anything you like, so long as it is unique.

execute= is the rtorrent command, in this case to execute a shell command.

/path/to/mail.sh is the name of our script (or whatever command you want to execute) followed by a comma separated list of all the switches/arguments to be passed.

$d.get_name= 'd' is an alias to whatever download triggered the command, get_name is a function which returns the name of our download, and the '$' tells rTorrent to replace the command with its output before it calls execute.

The end result? When that torrent, 'All Live Nudibranches', that we started before leaving for work finishes, we will be texted:

All Live Nudibranches: Done

Displaying active torrents

The rtorrent doesn't list the active tab properly by default, add this line to your .rtorrent.rc to show only active torrents

Locked Directories

Rtorrent can sometimes lock up after a crash or incorrect shutdown, and will complain about a lock file.
Per the error message, the file called "rtorrent.lock" can be found within the hidden folder /.rtorrentsession for your download directory and manually removed.

Web interface

There are numerous web interfaces and front ends for rTorrent including:

WTorrent is a web interface to rtorrent programmed in php using Smarty templates and XMLRPC for PHP library.

nTorrent is a graphical user interface client to rtorrent (a cli torrent client) written in Java.
